Chapters (5)
hmm, I am not sure I've read one quite like this before. I have read a repentant Pinkamena, and a few where she wasn't in control, but Equestria seems to be going mildly nuts. I am happy that you fixed Dash though.
You need to check your spelling errors and I see a bunch of them! Mainly the characters names are spelled wrong. twighlight should be Twilight. apple jack should be Applejack. Capitalized, spelled correct, and not spaced. You should space out the paragraphs. It's a wall of text right now. Remember that everytime a pony/person talks you need a new paragraph or line. Great story even if there are errors.
That's where practice comes in handy! Don't forget to add periods after the sentence is complete. I hope I didn't forget anything....
"I one them in a lottery smart one.". The 'one' should be 'won'. 'One' is the number and this 'won' is used as: "I just won the game!". I'm sorry if it sounds like i'm being too harsh or mean .
